PhD scholarship in Cascaded Design Tools for 10MW Offshore Wind Turbine Floaters

jobbeskrivelse:
DTU Wind Energy is seeking a PhD student for a scholarship on “Cascaded design tools for 10MW offshore wind turbine floaters”. The PhD scholarship is part of the LIFES50+ project funded by the EU Horizon 2020 programme. LIFES50+ aims at qualification methods for floaters that can support turbines of the 10MW class. The aim of the present PhD study is to develop new modelling techniques for offshore wind turbines that can complement existing aero-hydro-servo-elastic tools. Responsibilities and tasks Offshore wind energy is a key contributor to a carbon-free energy supply. An important step to make floating wind turbine technology economically feasible is the application of larger wind turbines and the ability to design the floater to minimum cost. Most designs of floaters for offshore wind turbines are today based on simulations of many 10-minute load cases. The applied state-of-the-art tools are known to be ‘quite accurate’, but are limited by approximations that make them operational at about real-time calculation speed. For an improved design process, however, faster tools are needed to enable optimization in the pre-design phase. Further, accurate high-fidelity (and thus CPU-demanding) tools are needed for the detailed component design. The PhD study The PhD study focuses on the development and validation of such models and their application to specific floater concepts within LIFES50+. Together with a post doc at DTU and in collaboration with University of Stuttgart, the PhD study will establish a set of models that cover both fast, state-of-the-art and high-fidelity tools. The tools are validated against experimental data and cross-validated against each other. Results from the LIFES50+ experimental campaigns in a wind tunnel and a wave basin, will be available for validation. Besides the actual modelling work, the research will focus on the physical effects modelled and the ability of the models to capture them. The model developments and validation will be within the following areas •forcing and response of floating structures to nonlinear and extreme waves •CFD modelling of viscous flow effects and extreme waves •parameterized aero-dynamic forcing models for efficient design •characterization of dynamic wake phenomena in the lab •low degree of freedom frequency domain methods for pre-design •charactization of scale effects between model tests and full scale •screening of model accuracy by cross-comparison between models and to experimental data The exact choice of developments for the PhD study will be decided between the PhD student and the research team, based on input from development needs from the other partners in LIFES50+. Qualifications Candidates should have a master's degree in engineering or a similar degree with an academic level equivalent to the master's degree in engineering.In the assessment of the candidates’ consideration will be given to: •Strong knowledge of aerodynamics •Strong knowledge of offshore hydrodynamics and wave-structure interaction •Sound physical insight and the ability to critically judge a set of results or measurements •Experience with development and application of aero-elastic models for floating wind turbines and numerical methods in fluids/CFD •Experience within analysis of experimental data and their use for model validation •Strong programming skills such as Fortran, Matlab, C •Collaborative skills •The ability to communicate at all levels such as the provision of scientific advice to public sector authorities Supervisor •Main supervisor: Henrik Bredmose, DTU Wind Energy Approval and Enrolment The scholarships for the PhD degree are subject to academic approval, and the candidates will be enrolled in one of the general degree programmes of DTU.
